"Marta is a young girl who saw thirty miles of barbed wire appear across her city overnight, separating Berlin into West and East--with Marta's home on the Communist Bloc-controlled Eastern side. Then, just a month ago, Marta's brother became a victim of schiessbefehl, the standing order to fire upon anyone who dared pass into the West. With her family and nation both fractured, Marta will soon be faced with a promising--but dangerous--opportunity. Is the desire for freedom enough to risk more death?"--OCLC.
